Ventilating when its cold outside?

Hi, this is going to be my first time and I'm still in planning and thinkin of putting my grow tent in the first room with a window close to it so the hot exhaust air could've gone straight out of it with ducting. But I realized I can't keep the window open all the time since its really cold outside and our apartment would get too cold like that. So could someone tell me where else could I blow out the hot air, into the other room??

Hey,
well technically as long as you pipe the hot(edit. Stale air) air outta the room with the tent, so it cant get sucked back into the tent you would be fine. So maybe through a wall,or celling. Or out the door,
Or just buy some boarding Nd mount that to the window, and have the ducting mounted to that. If you get me.

Take it easy.

make a block or board for the window that you can connect the ducting to it and you dont have open areas where cold air is blowing into your apt... dont know if that is an option

Hi guys,
Thanks for your replies. I don't really understand that, do you have any more precise instructions for building it?

I'm downstairs and took some plywood and cut holes for exhaust/intake. Right now, I only use 1, for intake, but don't have it hooked to the window all the time because it's very cold outside and the temps can get low, so most of the time now, it's sucking air from inside the room. Right now, I have the exhaust (going through a carbon filter) going into the basement to keep it warm, in the summer, I'll use the top exhaust port and blow it outside. Note, this window is in a basement well with a cover over the top, so you can't see it. That deal coming out of the cover is a Radon remover. Just something that came with the house. One reason why I had to build a custom window well cover.

Open your window. Or if you have to, remove the window.

Measure the open window space. Cut a couple pieces of 1/2" or thicker plywood that size. Or cut them oversize and pinch them in place by running bolts through. Assemble the two pieces of plywood by putting some scrap 2 X 4 between them and put this section of "hollow wall" back in the open window. It might be best to assemble it in place. Maybe you can use the window to slide back down and pin your plywood sandwich into place.

This may involve screws, bolts, caulking, insulation, duct tape, various widgets, and you're gonna have to do some thinking on your own. At some point yer gonna need to cut a hole through the plywood to accommodate your duct work.

Hi guys, I'll have to build that plywood board then. I was thinking on the upper part of this window,( the pic is sideways)

Yeah, that top window looks like it could be replaced with a board and small fan/over the ducting hole to conceal it from the outside and your good to go i would think.
Just so long as you have the ducting hole looking like a proper job no one will be the wiser..

take it easy.

^^^^ agree especially where he says "as you have the ducting hole looking like a proper job"

There are a few grow houses in my immediate area with exhaust vents blatantly obvious. It can be spotted a mile away by even the untrained eye. You can end up busted or ripped off if you're lazy venting out of a window without doing it so it looks right.

What do u mean small fan over the ducting hole?

Do you mean like an extractor fan on the window?

Hey,
no sorry i think you misunderstood what i ment by fan, like a cover fan you see, there plastic and no moving...
Sorry, my shity english(yes first language) , i mean a vent really, plastic vent. In the shape of a fan..}http://www.flickr.com/photos/93410621@N05/9109293813/
like that, or maybe...

just something to cover the inside of the ducting, also makes the board look normal you know...
im sure you will get it sorted.

take it easy and goodluck.

Yea I was just looking at fans like that online so I got it now lol.

And what is considered cold? Right now I've got a 2 inch central vac tube for my intake and outside temps are going to -30 C this evening. Mind you the fan is on a thermostat, so hopefully balance will easily be achieved. only running 2KW right now. Just getting my room up and running after some major downtime. lots a fun and challenges.

I have found that running consistent temps at both the high and low ends is somewhat challenging. Seems like it gets hot right prior to my exchange then really cool right after.

I think cold is below 60. I personally like it no cooler than about 68
